Abstract (en)
Provided is a continuously variable transmission mechanism of a traction drive type having: a shaft (60) which functions as the center of rotation; relatively rotatable first and second rotating members (10, 20) that are disposed to face each other on the shaft (60) and share a first rotation center axis (R1); plural planetary balls (50) that have a second rotation center axis (R2), are radially disposed around the first rotation center axis (R1) as the center, and are held between the first and second rotating members (10, 20); and an iris plate (80) that changes the gear ratio between an engine-side input shaft (11) and a drive wheel side output shaft (21) by tilting each of the planetary balls (50) with respect to the first rotation center axis (R1). When an engine is started, the gear ratio is controlled to an acceleration side rather than maximum deceleration.
